b. 48

composition: Op. 10 No 5, Etude in G♭ major

No sign in A

 in FE (→GE,EE)

Long accent suggested by the editors

..

According to us, the  mark added in a proofreading of FE (→GE,EE) is a long accent, misunderstood by the engraver. Cf. the Etude in A minor, No. 2, bars 8, 12 and 17.

b. 50-54

composition: Op. 10 No 5, Etude in G♭ major

No pedalling in A

Pedalling in FE (→GE1)

Our suggestion

GE2 (→GE3GE4GE5) & EE

..

The pedal marks in bars 50 and 54 were added by Chopin in a proofreading of FE (→GE1). Lack of  in bar 54 seems to be a result of an oversight, therefore, we add it under the 2nd quaver (the main text, after the pedalling of FE in bar 6) or under the 3rd quaver (an alternative suggestion, based on the pedalling of FE in bar 14 and adopted in bar 54 already in EE and subsequent GE,s).
